This week-long course is especially appropriate for 4th and 5th grade teachers who have previously taken Understanding Energy One. The course will include working with concrete materials in order to more fully understand the concepts of energy transfer and transformation and conservation of energy in systems, as delineated in the new science standards. A major focus will also be on the energy present in the following science units: Circuits and Pathways, Ecosystems, Models and Designs, Microworlds, Food Chemistry, and Land and Water.
